The purposes of this study were firstly to optimize the recipe for iced cookies by cooking with five different ingredient levels of $Jinuni\;bean(X_1),\;butter(X_2)\;&\;sugar(X_3)$ and secondly to analyze the chemical and sensory test results by using RSM(Response Surface Methodology). As a result of this test, water activity decreased with increasing contents of butter or sugar, while hydrophilic browning decreased independently with increasing sugar content. There was a positive correlation(p<.001) between specific gravity and hardness, although the result was not uniform due to the interaction of each factor. There was a negative correlation(p<.001) between the spread ratio and gravity or hardness, and it tended to increase with increasing each content. Color value L and color value a had positive correlation (p<.001) and the value tended to decrease with increasing the quantity of Jinuni bean. Generally, the strength of the cookies showed a saddle point at the peak of the 3d graph. As a result of sensory evaluation, the color was sensitive to the contents of sugar and Jinuni bean, the texture was sensitive to the contents of butter and sugar, and the taste and overall quality were sensitive to all three factors. Color had a positive correlation(p<.05) with the taste, texture and overall quality. There were high positive correlations(p<.001) between the taste, texture and overall quality. The preference data showed an up-swollen, parabolic shape in the center of the 34 graph, which enabled the optimum value to be determined and the optimum mixture ratio which fulfilled all sensory items was Jinuni bean 93g, butter 188.5g and sugar 155g, indicating a substitution of flour by $44\%$.

This study aimed to reduce the oily taste of Bechamel sauce, and improve consumers' acceptability and functionality by adding Ginseng seed inside. This study also performed quantitative description analysis and acceptability test in order to see its unique sensory characteristics. The results were as follows: The viscosity and moisture content decreased as ginseng seeds got added. This may be due to decrease in relative amount of flour. In terms of color, brightness (L) and yellowness (b) tended to decrease as ginseng seeds were added, while redness (a) showed just the opposite propensity. The salinity became higher with more ginseng seed, however, soluble solid content showed no significant difference among the samples. From the result of quantitative and descriptive analysis among the sensory tests, the concentration of Bechamel sauce got higher with more ginseng seed, where the fragrance and the taste of ginseng were sensed strongly, while fragrance of milk, flour, and nuts were considered weak. Also, sense of stuffiness, oiliness, and tenderness has decreased as well. From the acceptability test, adding 30% of ginseng seed got the highest ratings in terms of fragrance, taste, afterward-taste, and overall acceptability. Therefore, adding ginseng seed positively affected Bechamel sauce in taste, smell, after-taste, and general acceptability. Moreover, when the added amount of ginseng seed was 30% compared to the flour, the taste of Bechamel sauce was relatively optimized. From the test results, it can be concluded that ginseng seed injected in Bechamel sauce improved nutritive facts and the taste acceptability as well, and 30% compared to the flour amount was the right amount to maximize consumers' acceptance of Bechamel sauce.

BACKGROUND/OBJECTIVES: Bitter taste receptors are taste signaling pathway mediators, and are also expressed and function in extra-gustatory organs. Skin aging affects the quality of life and may lead to medical issues. The purpose of this study was to better understand the anti-skin aging effects of bitter taste receptors in D-galactose (D-gal)-induced aged human keratinocytes, HaCaT cells. MATERIALS/METHODS: Expressions of bitter taste receptors in HaCaT cells and mouse skin tissues were examined by polymerase chain reaction assay. Bitter taste receptor was overexpressed in HaCaT cells, and D-gal was treated to induce aging. We examined the effects of bitter taste receptors on aging by using β-galactosidase assay, wound healing assay, and Western blot assay. RESULTS: TAS2R16 and TAS2R10 were expressed in HaCaT cells and were upregulated by D-gal treatment. TAS2R16 exerted protective effects against skin aging by regulating p53 and p21, antioxidant enzymes, the SIRT1/mechanistic target of rapamycin pathway, cell migration, and epithelial-mesenchymal transition markers. TAS2R10 was further examined to confirm a role of TAS2R16 in cellular senescence and wound healing in D-gal-induced aged HaCaT cells. CONCLUSIONS: Our results suggest a novel potential preventive role of these receptors on skin aging by regulating cellular senescence and wound healing in human keratinocyte, HaCaT.

This study examined dietary behaviors such as use motive, selection attribute, satisfaction, and purchasing intention in Yaksun foods according to women's dietary life style type. To achieve this research objective, it targeted women in more than the 20s who dwell in Seoul and Busan area. As a result, the following facts were clarified. First, the highest recognition was shown in rationality-seeking type as for diversion and in taste-seeking type as for sociality among the motives for using Yaksun foods. Second, the highest recognition was shown in taste-seeking type as for food quality & taste and physical service and in rationality-seeking type as for convenience among the selection attributes of Yaksun foods. Third, the satisfaction and the purchasing intention of Yaksun foods were the highest in health-seeking type. Seeing the above findings, the differentiation will be pursued from other food-service markets by making sensual taste and flavor as the food materials of Yaksun foods targeting consumers who pursue taste. Also, to increase satisfaction and purchasing intention of Yaksun foods, there is a need to positively publicize that Yaksun foods have efficacy on maintaining health and preventing disease.
